The tools and platforms that enable sustainable web.
100% renewable energy, PUE 1.2, located in Germany.
Efficient container management without overhead.
Automatic code splits, image optimization, edge caching.
We use the CO2.js standard from the Green Web Foundation, which accounts for data transfer, energy mix, and device efficiency. Each page is analyzed regularly.
No. Optimized websites are often cheaper to operate due to lower hosting costs, and better performance leads to higher conversion rates.
An average website produces 1.76g CO₂ per view. Our pages range from 0.15-0.35g – a savings of 80-90% while delivering better performance.
Hetzner uses 100% renewable energy. Additionally, we optimize code to minimize computational load. Together, this creates a sustainable solution.
